I would like to share a problem I face when I have to install a surge protection device type 1 in high power electrical switchboard. I already asked this question on another blog, and I’m trying to get more feedbacks from electrical engineers.
The situation is very “unconfortable” for me as a quality provider, because if a short-circuit of high value happens, though luckily probability is low, it would mean very serious safety risks …

It’s Good to have in mind practical aspects: case of a low voltage switchboard To achieve the effective installation of the surge protection, the surge arrester’s connections to the grid should be as short as possible. Any cable crossed by a lightning impulse current has a significant voltage to be added to the Surge Protection Device (SPD) residual voltage.

Many Electrical Contractors and Panel builders ask this question.
